ELECTRIC BATTERY.

SPECIFICATION forming part of Letters Patent. No. 715,920, dated December 16, 1902.

Application filed April 30,1902. Serial No. 105,281. (No model.)

l'o all whom, t may concern- Be it known that I, DAVID H. WILSON, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Batteries, of which the following is a specification.

My invention relates to electric batteries, and has for its object to provide a new and improved battery of this description.

My invention is illustrated in the accom panying drawings, wherein- Figure 1 is a View of a battery embodying my invention. Fig. 2 is a section therethrough. Fig. 3 is a plan View.

Like letters refer to like parts throughout the several gures.

In making up my battery I provide an ordinary outer cup or jar A of any desired material. Within this jar is placed the electrode B, preferably of zinc or some analogous metal. This electrode is preferably cylindrical in shape. The other electrode O is preferably of carbon. This electrode is arranged so as to surround the electrode B, as it were, and have opposing faces opposite both the exposed faces of said electrode. As illustrated in the drawings, the electrode O may be said to consist of two cups C and C2, integral with each other and separated by a space, the electrode B being received in this space. For purposes of illustration I have shown these cups orv receptacles as circular; but it is of course evident that they may be of any other shape. Said electrode B has a projecting part B', which extends through the t connecting portion O3 between the two cups O and C2, said portion provided with a terminal B2 for the conductor leading from the battery. This projecting part B is properly insulated from the electrode O. The electrode C is provided with a suitable terminal C4 and is supported by the connecting portion C3, which extends beyond the cup C2 and rests upon the edge of the jar A. As illustrated in Fig. 2, the cups C and C2 open in opposite directions, as it were. In other words, the open ends of said cups are at opposite ends of the electrode. I prefer to vcopper-plate the face of the connecting portion O3, and I may also cover it. with paraffin. Any suitable depolarizer is placed within the cup C' and the active solution is placed in the jar'A, so as to be contained within the cup C2 and around said cup when the parts are in their proper position. The cup C2 surrounds the cup O,'as shown. By this construction I get a large area of electrodes and I am enabled to provide a battery which produces a large quantity of current at a coniparatively high voltage. This battery also has a low internal resistance and other advantageous features.

I have described the construction in detail; but it is of course evident that the parts may be varied in certain particulars, and I therefore do not limit myself to the device shown and described.

I clairn- 1. An electrode for electric batteries, comprising two cups or receptacles integral with each other and separated by a suitable space, said cups or receptacles opening in opposite directions.

2. An electric battery, comprising an electrode consisting'of two cups or receptacles integral with each other and opening in opposite directions, said cups or receptacles separated by a space, and a second electrode contained within said space so as to be opposed to the faces of both of said cups..

- 3. An electrode for electric batteries, comprising two carbon-cups opening in opposite directions and separated by a space, and a connecting-piece between the cups integral with both cups.

4. An electrode for electric batteries, com-v prising two carbon-cu ps opening in opposite directions and separated by a space, and a connecting-piece between the cups integral with both cups, said connecting-piece adapted to act as a support for the electrode.
